==== Change parameter using command line: ====
First check the parameters set to the port:
switch1-distrib1# show running-config interface Gi1/0/47
Building configuration...
Current configuration : 84 bytes
!
interface GigabitEthernet1/0/47
description none
switchport access vlan 1
end
Update the parameters of the port using grant access:
switch1-distrib1# conf t
switch1-distrib1(config)#interface Gi1/0/47
switch1-distrib1(config-if)#desc wifi1
switch1-distrib1(config-if)#switchport access vlan 7
switch1-distrib1(config-if)#no shut
switch1-distrib1(config-if)#end
Save your change permanently:
switch1-distrib1# copy running-config startup-config
switch1-distrib1# exit
==== Change parameter on an etherchannel using command line: ====
